JHEADLIGH'J! Fongvnnrcrfns v Application med June 15, i929.,y serial No. 371,219.:

.This invention relates to improvements in headlights and particularly to those used on motor vehicles. j

Its chief object is the provision of a headlight which is so designed and constructed as to effectually cut oft1 or deflect the direct and reflected glaring rays and prevent them from shining into the eyes of approaching motor-` ists and pedestrians. i

Another, object of the invention is to provide a deector or non-glaring attachment for headlights of this character which is simple, compact and inexpensive in construction, and which can he applied to ordinary headlights. n

In the accompanying drawings:

Figure 1 is a frontwview of a headlight embodying my invention.I Figure 2 is a vertical section thereof taken on line 2-2, Figure l.

Figure 3 is afragmentary vertical section on line 3 3, Figure 1. Figurei is a detached perspective view of the deilecting partitions Similar characters of reference indicate corresponding parts throughout the several views. Y

The body of the headlight may be of any appropriate and well known construction, that shown in the drawings, by way of example, consisting of a shellor casing l0, a parabolic reflector 11 and an electric lamp 12.

Disposed within the lamp-chamber formed by the reflector 11 and projecting forwardly therefrom. are intersecting partitions or deflectors 13, 14 lwhich are preferably disposed at substantially right'angles to each other and krwhich intersect along the center line of the lamp. The inner edges of the deilectors are shaped to the contour of the reflector 11 to t snugly against it and they' are cut away or notched as indicated at 15 to fit about the lamp 12. As seen in Figure 2, these intersecting'deliectors project a suitable distance beyond'thefront side of the lamp-casing and may be exposed as shown, or protected from the weather in any appropriate 'mannen Fitted into the quadrant-like spaces formed by the, deiflectors are lenses 16 which'may be held at their inner edges by lugs 17 struck up from the defiectors and at their outer edges by the customary holding rim 18 applied tothe front'side of the casing 10. j

' TheA deflecting partitions* "13, 14 may be made of sheet metal or other suitable-material and be constructed in theform of an attach-VV ment for existingflamps or made. a permanent partof anew lamp. Said partitions forma plurality o'f light-emitting' passagesand the faces 19, 20, 21 and 22 thereof are preferably made4 dull or blackened so as'not to reflect the direct or reflectedrays'of light issuing vfrom the lamp into the eyes of approaching drivers, while the remaining faces of the deflectors 'may be polished to deflect the rays to advantage downwardly and'to the right `of the car out of the path of approaching vehicles.

i Disposed in the lower-corner of the upper right hand quadrant formed by the deflectors 13, Mandat apoint immediately infront of the lamp 12 is la `light'f-intercepting shield 23 .which is of the proper'area to effectively block off the direct rays projected from the upper righthand portion of the 4lamp and prevent their shining linto the eyes vof approaching autoists or pedestrians. Likewise, the stray rays usually reflected' from the lower lefthand side lof the parabolic reflector 11 directly'into the eyes of approaching drivers, I provide` a l. second light-intercepting or segmental' shield 24 which is Vdisposed diagonally opposite thershield 23'in the manner shown in Figure 1 and which may beproduced'by darkening or' painting the 'outer arcuate portion of the corresponding lens 16. The area of the arcuate portion 24 is such-that it does not interfere with the projection of those reflected rays whichshine on to the roadway. i' Whileamanifestly simple and inexpensive in construction, ithis'gimproved headlight, while affording ample roadY illumination in front of the car as well as to the right thereof,

to "prevent eii'ectually eliminates glaring rays shining y gerousstray or reflected rays as well.

Y I claim as my invention v1. TheP Combination with a headlight having la ,reflector and a source oflight, ofKA intersecting detle'ctors disposed .substantiallygin projecting forwardly from said re'ec'tor, and

yspaced quadrant-shaped light passages, a light-intercepting shield disposed at the inner corner of one of said light passages and transversely of adjoiningVdefiector-Walls, and a second lightintercepting shield disposed in the diagonally opposite light passage and forwardly of the first-named shield, said second shield extenng Ltransversely between .thedivergent edges of the adjoining defiector-walls and from the corner thereof.
